Wrath of Logarius formed in San Francisco, California, having evolved from the project Martyr Logarius, and signed with Season of Mist ahead of their 2023 EP Necrotic Assimilation. The band describes their approach as "formless black metal," navigating between raw black metal, brutal death metal, and post-metal textures without settling into a fixed genre identity. Named after the boss character from the video game Bloodborne, the project earned early attention for its layered and eerie compositional sensibility within the Season of Mist underground division.

Los Angeles heavy metal band formed in 2025, straddling the line between hard rock energy and traditional heavy metal weight in a city with a deep legacy of both. A brand-new act arriving on the LA scene with the hard-rocking, riff-driven sensibility of the genre's classic era.

Los Angeles avant-garde black metal duo formed in 2017, notable for replacing conventional guitar with grand piano as the primary instrument alongside drums and shrieked vocals. The result is a genuinely strange, dissonant take on black metal that sounds like nothing else in the California underground.

San Diego death metal and grindcore band formed in 2023, operating out of Southern California's second-largest city with a sound that fuses grindcore's hyper-compressed violence with the riff architecture of old-school death metal. A young act already tapping into the city's historically fertile underground extreme scene.

An Oakland, California death metal band formed in 2022, whose name sets the tone perfectly — this is fetid, deliberately unclean death metal in the tradition of the Bay Area's more grotesque underground. The filth is the point, and they lean into it with enthusiasm.

San Jose, California's Wrvth have one of the more interesting trajectories in extreme metal, beginning as a technical death metal and deathcore act before gradually shifting toward progressive post-metal and metalcore over the course of their career since 2010. The evolution is genuine rather than expedient, with each era of the band producing work that's stylistically distinct but consistently ambitious.

Sacramento's Wurm Flesh traffics in technical brutal death metal, building walls of churning riff work and precision blastbeats into compositions that are as surgically disorienting as they are relentlessly punishing. Formed in 2018, they represent the Californian tradition of brutality pushed through a technical lens.

Los Angeles black metal newcomers Wyrmtongue launched in 2024, bringing a harsh and uncompromising approach to the genre from within one of North America's most unlikely metal hubs. Their presence in the LA underground signals an interest in bleakness and extremity over the city's more polished heavy fare.

Formed in Oakland, California in 1974 as Yesterday and Today, Y&T are among the most accomplished hard rock acts to emerge from the Bay Area, releasing two albums on London Records before shortening their name and signing to A&M Records in 1981. The trio of albums Earthshaker (1981), Black Tiger (1982), and Mean Streak (1983) represent their commercial and artistic high point, fueled by guitarist and vocalist Dave Meniketti's expressive playing and the band's melodic hard rock craftsmanship. In Rock We Trust (1984) became their best-selling record, and the band has sold over four million albums worldwide despite never achieving the mainstream prominence their craft warranted.
